摘要
目的 探讨老年高血压病及脑卒中患者动态血压的特点。方法 对 30 7例高血压病患者进行动态血压监测 ,并根据年龄分为 :A组 (对照组n =16 1) ,年龄 <6 0岁 ;B组 (观察组n =14 6 ) ,年龄≥ 6 0岁。两组中又根据是否合并脑卒中 ,进一步分为 4个亚组A1 、B1 组 (无脑卒中 ) ,A2 、B2 组 (脑卒中 )。结果 B组老年高血压患者无论有无脑卒中 ,其血压昼夜节律性明显低于A组 (P <0 .0 5 )。B组脉压 [B1 组昼脉压 5 2 .9mmHg(1mmHg =0 .133kPa) ,夜脉压4 9.4mmHg;B2 组昼脉压 5 3.2mmHg ,夜脉压 5 3mmHg]较A组脉压 (A1 组昼脉压 4 3.6mmHg ,夜脉压 4 0 .3mmHg ;A2组昼脉压 4 7.2mmHg ,夜脉压 4 4mmHg)明显增大 (P <0 .0 5 )。B2 组夜间收缩压 (12 8.1mmHg)明显高于其余 3组 (A1组 117.4mmHg、A2 组 12 1.1mmHg、B1 组 12 0 .7mmHg ,P <0 .0 5 )。结论 血压昼夜节律降低。
Objective To study the feature of 24 hour ambulatory blood pressure monitoring (ABPM) in elderly patients with essential hypertension and stroke.Methods 307 patients with essential hypertension were divided into two groups:group A (age<60 years,n=161);group B(age≥60 years,n=146).According to the patients with or without stroke both groups were further divided into 4 subgroups:A 1 (without stroke),A 2 (with stroke),B 1 (without stroke) and B 2 (with stroke).All subjects were examined by ABPM.Results The incidence of non dipper type blood pressure in group B was significantly higher than that in group A [79% (115/146)vs 61% (98/161)].The pulse pressure(PP) in group B was significantly higher than that in group A (PP of day in group B 1 was 52.9 mmHg and in B 2 was 53.2 mmHg,PP of night in group B 1 was 49.4 mmHg and in B 2 was 53 mmHg)(P<0.05 and P<0.001,respectively).Night SBP in subgroup B 2 was significantly higher than those in the other subgroups(128 mmHg vs 117.4 mmHg,121.1 mmHg and 120.7 mmHg)(P<0.05).Conclusion The features of ABPM in elderly hypertension patients are abvious changes of blood pressure circadian rhythm and pulse pressure.
